If you're asking that Extend Frame apply to more that the single highlighted track, I really don't see that happening.

When I've been in this situation, I just extend the track as needed, then highlight all the other elements that need to move (Shift key + left mouse click on each*) so that they all move together and stay in sync.

*It it's a lot of timeline elements, it may be faster to select all (Ctrl+A) then subtract (Ctrl+click) the items that don't need to be moved.
